Temple of Mithras in Sirmium

The Temple of Mithras in Sirmium was a temple that celebrated one of the mystery cults from the east that a large part of the Roman Army adopted. Mithraism prevented the worship of other gods, so the 12,814 Sirmians worshipped the one cult. In 372 AD, Governor Luca Flavius had the temple destroyed to be replaced by a Christian abbey.
